Re: [Discuss-gnuradio] [Douglas Geiger BBN 802.11b] Porting code on USRP2 problems

[Colby Boyer]

Hi All,

I've been trying to run some hardware tests between two USRP2s, but I have had no success in receiving packets. I am using the modified TX from Tiago.  I feel sorta confident that the TX code works, because when I run the usrp2_fft.py, I see a wave form being transmitted over the channel.

Has anyone have any success on receiving packets between two USRP2s? When RX/TX there is a usrp2::ctor reset db failed error. Could this cause problems for the RX/TX? I am using the firmware that was shipped with the USRP2.

Thanks,
Colby Boyer

Hi all,

Since I have tested the tx code (bbn_80211b_tx_port2.py), I wanted to run the bbn_80211b_rx.py inorder to capture the packets sent but I encountred this error:

TypeError: usrp2_source_32fc_sptr_set_decim() takes exactly 2 arguments (1 given)

do you have any idea about the origin of this problem? Thank you in advance.
